After setting the registry; rebooting and setting the AHCI in the BIOS. If you re-run the assessment it only ran the hard drive only. The secound time rebooting I ran the assessment again and it ran the whole series of tests. No errors. So we need to reboot twice?
I saw no improvement for Sata hard drives.

Yes, change the reg entry and reboot to change the BIOS then install the drivers then reboot again to finish; so you got it sorted?

Thanks for the help. One other question, since I already have Windows 7 installed and I didn't haveAHCI turned on the drivers weren't loaded. How do I get the drivers loaded now? Thanks again for the help, Atlcraig

hello,
isnt it possible to have raid and ahci activated at the same time??

Raid actually runs under AHCI, If you want to continue using RAID don't change to AHCI.

You can run in RAID with no drives in actual RAID, and get the benefits of AHCI.

Quote:

Many SATA controllers offer selectable modes of operation: legacy Parallel ATA emulation, standard AHCI mode, or vendor-specific RAID. Intel recommends choosing RAID mode on their motherboards (which also enables AHCI) rather than the plain AHCI/SATA mode for maximum flexibility, due to the issues caused when the mode is switched once an operating system has already been installed.[2] Legacy mode is a software backward-compatibility mechanism intended to allow the SATA controller to run in legacy operating systems which are not SATA-aware or where a driver does not exist to make the operating systems SATA-aware.

I have changed the setting with regedit and created a restore point in windows 7. I then went into the BIOS and enabled AHCI. When I booted the system up after that I got themessage ERROR LOADING OS and now can't get the computer to boot. I had to get on one of my other computers to get back here. I need help now. Can anyone give me an idea on what I need to do now?????
